Abstract

The invention provides composite cover plate glass. The composite cover plate glass comprises cover plate glass and a waterproof layer compounded on the outer side of the cover plate glass, the waterproof layer comprises a waterproof base material layer and a lotus leaf vein-shaped texture layer formed on the surface of the waterproof base material layer; and the waterproof layer is selected from one or more of MgF2, LiF, thorium fluoride (ThF4), Na3AlF6 (cryolite) and ZrF4. According to the invention, a specific kind of waterproof material is prepared into the texture layer with the lotus leaf vein-shaped structure, so that high-efficiency waterproofing can be realized, the stability of the module battery is improved, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of conductive thin films, and in particular relates to a preparation method and application of a conductive electrode and a composite cover glass. Background technique [0002] In the crystal structure of organic-inorganic hybrid perovskite materials, organic components and inorganic components are connected by hydrogen bonds. This weak bonding method fundamentally determines its poor intrinsic stability. For mainstream device structures, moisture in the environment can permeate into the perovskite active layer through diffusion, causing irreversible damage to device performance. At present, the photoelectric conversion efficiency of perovskite solar cells certified by the National Renewable Energy Laboratory is still marked as an unstable efficiency. Although the causes of the decomposition of perovskite materials have been extensively studied, the lack of long-term stability of perovskite photovoltaic dev...
